Factuarea APIDevelopers

Provision a managed account

Provision a SEPARATE account for one of your clients, with its tax ID, plan and your access_level; your account pays it. - Returns 201 with the claim voucher shown EXACTLY ONCE, or emailed with send_email: true. - Repeating an external_ref returns 200 with no new voucher; Idempotency-Key is required. - Requires the privileged accounts:write scope.

Headers

Idempotency-Key*string

Client-generated opaque key (up to 255 characters; UUID v7 recommended) that makes retries safe: the first response is cached and replayed for repeats without re-executing the mutation. Reusing a key with a different body returns 422 idempotency_key_reused; the values of secret fields (password, secret…) count as part of the body, so retrying with a corrected secret under the same key is a different request, never the replay of the earlier answer. See the Idempotency guide. Required on this operation: repeating it delivers an effect that cannot be taken back (an email sent, a file generated, a third-party call, a charge), so a request without this header is rejected with 422 idempotency_key_required before any business logic runs.

Length1 <= length <= 255
Factuarea-Version?string

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.
